What Researchers Did
This study aimed to identify the incidence, risk factors, and management strategies for pharyngocutaneous fistula after total laryngectomy procedures.
What They Found
The overall incidence of pharyngocutaneous fistula was 24.4%, with rates of 19.0% for primary laryngectomy, 28.6% for salvage laryngectomy post-radiotherapy, and 30.3% for salvage laryngectomy post-chemoradiotherapy. Multivariate analysis showed relative risks of 2.47 for hypoalbuminaemia, 3.09 for salvage laryngectomy post-radiotherapy, and 7.69 for salvage laryngectomy post-chemoradiotherapy. In the salvage laryngectomy post-radiotherapy group, conservative management, adjuvant hyperbaric oxygen therapy, and surgical closure were equally distributed as treatments.
What This Means for Canadian Patients
Canadian patients undergoing total laryngectomy, particularly those who have received prior radiation or chemoradiation, face an elevated risk of developing pharyngocutaneous fistula. Recognizing these specific risk factors can help surgeons in Canada implement preventive measures and choose appropriate treatment plans, potentially including hyperbaric oxygen therapy for radiation-related complications, to improve patient recovery and reduce hospital stays.
Canadian Relevance
This study is not Canadian. However, it discusses the use of adjuvant hyperbaric oxygen therapy for pharyngocutaneous fistula following salvage laryngectomy after radiotherapy, which relates to the Health Canada-recognized indication of delayed radiation injury.
Study Limitations
The findings of this study are based on a retrospective, match-paired analysis, which may be subject to inherent biases and limitations in data collection.
